15 SERIAL SIGNAL SWITCH
15.1 General
Two main blocks are implemented in the CL RC632. A digital circuitry, comprising state machines, coder and
decoder logic and so on and an analog circuitry with the modulator and antenna drivers, receiver and
amplification circuitry. The interface between these two blocks can be configured in the way, that the
interfacing signals may be routed to the pins MFIN and MFOUT.
This topology supports, that the analog part of the one CL RC632 may be connected to the digital part of
another device.
The serial signal switch can be used to measure MIFARE and ISO14443 as well I
CODE1 and ISO15693
related signals.
Note: The MFIN pin can only be accessed by 106 kbaud according to ISO14443A . The Manchester
with Subcarrier- and the Manchester signal can only be accessed at the MFOUT pin at 106 kbaud
according to ISO14443A.
15.2 Block Diagram
Figure 15-1 describes the serial signal switches. Three different switches are implemented in the serial signal
switch in order to use the CL RC632 in different configurations.
The serial signal switch may also be used during the design In phase or for test purposes to check the
transmitted and received data. Chapter 21.2 describes analog test signals as well as measurements at the
serial signal switch.
Note: The SL RC400 uses the name SIGOUT for the MFOUT pin. The CLRC 632 functionality includes the
